preloading images for jcarousel and other 'slide shows' was the reason
I wrote traverseDir it takes removes the need for jcarousel's built in
external file of images for the automatically generated pages from my
apache server. I didn''t like the delays that were present when it
went to get the next few pictures.
traverseDir is at http://jpassoc.com/demo/traverseDir/ and while I'm
not currently using jcarousel at the moment, my dog's site does
similar slide shows (1 at a time), the code
try {var img = new Image();img.src = url} catch(e){};
for each file seems to get the loads all pre-fetched!
The big question I had to answer was will the user actually look at
all those pictures? Or, should I get the images on demand, but get a
little delay.

Hi there,
Firstly, thanks very much for jcarousel.
I have an issue with using it - there's currently 103 images to load and
this amount will grow over time.
The problem I'm having is that I always need to display the 3 most recent
images upon hitting the page - in this case, the start items need to be
image 101, image 102 and image 103. I can do this no problem but the
initial scroll to images 101-103 shows empty spaces since image 1 to 100 are
loading sequentially in the background.
Ideally, I'd like to make this dynamic ie, loading 3 images at a time rather
than the current long list of images 1-103 (either within the page or using
an external .txt file).
So, can this be done by calling a page on the server to return the 3
required images (either the next 3 or previous 3) or is there a way to
preload the images either using a dynamic method (3 at a time) or the whole
103?
Hope that makes sense.
Thanks,
djl
